Diono Monterey 4DXT Latch 2-in-1 High Back Booster Car Seat

The Monterey 4DXT is the next generation of boosters, engineered with 15 upgrades to the award-winning Monterey model. From the remodeled headrest to the contoured seat base and breathable exo-shell panels, every detail has been carefully considered to create a contemporary new look. The Monterey 4DXT adjusts and expands as your child grows, offering wonderful all-round protection up to 12 years of age.

The height and width of the booster can be adjusted independently to ensure a safe and secure fit. The simple-to-use dial on the back allows for easy adjustments, while the headrest can be raised up to 6.4 inches with just one hand. The remodeled headrest is lined with thick EPP foam for better child comfort and improved side impact performance, complemented by deeper side wings and Diono's 4-layer Side Impact Protection System.

Safety is paramount, and Diono has engineered every detail to keep your little one safe, mile after mile. The EPP foam coating, molded rigid shell casing, and EPS coated outer shell work together to provide superior protection. The ergonomically contoured seat base, with luxury AIRTEK foam cushioning, improves the child's seating position for total comfort. Breathable exo-shell side panels enhance airflow to keep them cool on the move.

In addition to the exceptional safety features, the Monterey 4DXT offers practical and user-friendly design. The width of the vehicle seatback has been reduced to make installation easier, improving access to vehicle seatbelts and promoting independent buckling. The backrest can be easily removed, transforming the booster into a backless design when your child is ready to graduate.

Like all Diono boosters, the Monterey 4DXT is built to last, with up to 8 years of reliable service. The easy-adjust 11-position headrest and expandable backrest, with 4 layers of SafePlus Side Impact Protection, ensure that the booster grows with your child from 40 to 120 pounds.

Additional features include two built-in retractable 2-in-1 cup holders and snack trays, and premium soft fabrics with layered foam padding that can be easily removed for machine washing. The SafePlus belt guides and secure LATCH installation make the Monterey 4DXT a hassle-free choice for your child's safety and comfort.

When it comes to your next booster, the Monterey 4DXT from Diono is the one-stop solution that will take your child on their journey in safety and style.
